Grain harvester multi-angular inclined delivery conveyor and drive

摘要

A grain delivery conveyor for a grain tank of an agricultural combine includes a first gear box including a first input connectable in rotatably driven relation to a rotatable power source for rotation about a first axis, and a first output rotatable about a second axis angularly related to the first axis by rotation of the first rotatable input; a second gear box including a second rotatable input connected in rotatably driven relation to the first output for rotation about the second axis, and a second output rotatably driveable about a third axis angularly related to the second axis by rotation of the second rotatable input; and an elongate conveyor assembly connected in rotatably driven relation to the second output, the second gear box and the conveyor being jointly pivotable about at least the second axis for varying a position of a free end of the conveyor relative to the grain tank.
